How do you usually make onion oil juice in hotels? Don't use those materials and spices to answer questions on the computer.

J hasn't seen how they do it, but it's simple. Heat the oil, put pepper (I can put star anise if I like that flavor, but I won't put it if I don't like it), stir-fry until fragrant, then stir-fry chopped green onion, and filter out the chopped green onion. Leave the oil, make scallion cakes, or steam the fish. It's delicious! ! ! ! !
